Healthy aging is about healthspan, the years lived in good function, not just lifespan. At PHI in Beverly Hills, board-certified physicians Dr. Faisal Lalani and Dr. Nadiv Samimi offer the medical layer of longevity care, peptide therapy, NAD+, IV therapy, and red light therapy, alongside the lifestyle foundations and your broader longevity team.
Aging Well Is a Different Goal Than Living Longer
There are two ways to think about longevity. The first is lifespan, the total years lived. The second is healthspan, the years lived in good health, with full function, mental sharpness, and the capacity to do what you want. The two are not the same.
For most thoughtful patients pursuing longevity care, healthspan is the actual goal. Living to 95 with the function of a 75-year-old is what the conversation is really about. What we offer is the medical layer of healthspan-oriented care: physician-evaluated, physician-administered protocols that work alongside the foundational lifestyle factors that matter most, with honest framing about which treatments have established evidence and which are still emerging, and coordination with your primary care, specialists, and lifestyle providers.
What Actually Drives Healthy Aging
The science of aging has advanced significantly in the past decade, identifying specific biological processes that contribute to age-related decline: mitochondrial dysfunction, cellular senescence, chronic low-grade inflammation (sometimes called inflammaging), hormonal changes, oxidative stress, telomere shortening, loss of proteostasis, and stem cell exhaustion.
Each of these is partially modifiable through some combination of lifestyle factors and selected medical interventions. The most evidence-supported levers are lifestyle: sleep, nutrition, exercise, stress management, and social connection. Medical interventions add value on top of those foundations. We are honest that longevity medicine still has more mechanistic rationale than long-term human outcome data, and we pursue what evidence supports rather than what is trendy.
Where PHI Fits in Longevity Care
PHI is one component of comprehensive longevity care, not a complete longevity practice. We provide the medical interventional and regenerative side, particularly physician-administered peptide therapy, NAD+ therapy, IV therapy, red light therapy, and body composition support, coordinated with your other longevity-focused providers.
We do not provide comprehensive primary care, mental health care, nutrition counseling, personal training, or long-term metabolic management. For patients building comprehensive longevity programs, PHI is one piece that works alongside your other providers rather than trying to be everything.
How PHI Approaches Longevity Care
The first step is a comprehensive consultation: a detailed history of your health, family history, and goals, a discussion of your current lifestyle and foundational practices, review of any prior workup, an assessment of which medical interventions fit your situation, and an honest discussion of expectations and evidence. We do not sell broad packages; each program is built around your specific goals and baseline.
Peptide therapy uses specific compounds that target different systems (sleep, growth hormone signaling, tissue repair, mitochondrial function, inflammation); we discuss options individually without listing specific peptides publicly. NAD+ therapy delivers a coenzyme involved in cellular energy production and DNA repair that declines with age, with strong mechanistic rationale and accumulating clinical evidence. IV therapy delivers nutrients directly into circulation for documented deficits and cellular support. Red light therapy may support cellular function, mitochondrial health, and skin condition. These treatments are delivered in our clinic setting, and we coordinate with your broader longevity team.
Why PHI for Longevity Care
Two board-certified physicians
Dr. Faisal Lalani and Dr. Nadiv Samimi both trained at Cedars-Sinai and bring medical rigor and clinical sophistication to longevity care, meaningfully different from wellness clinics without physician leadership.
Evidence-aware approach
We are honest about which interventions have established evidence and which are emerging. We pursue what the evidence supports rather than what is trendy, and we do not promise lifespan extension.
Physician-supervised, clinic-setting delivery
Peptide therapy, NAD+, IV therapy, and red light therapy are delivered in our clinic setting under physician supervision.
Tailored programs
Each patient gets recommendations matched to their specific goals, baseline, and existing care. We do not sell standardized packages.
Coordination with broader longevity care
PHI fits within a multi-provider longevity team, working alongside primary care, specialists, nutrition, and fitness rather than replacing them.
Concierge, coordinated care
Single-physician continuity from consultation through treatment and return to activity. Patients receive clear guidance and transparent pricing at consultation.
Frequently Asked Questions
Sleep, nutrition, exercise, stress management, and meaningful social connection. The lifestyle foundations matter more than any medical intervention. Patients who optimize these often need less medical optimization than they expect; patients who skip them and rely on treatments alone consistently underperform their potential.
Honestly, we do not know definitively. Mechanistic rationale supports several treatments for the systems that affect aging. Whether this translates to longer life or simply healthier aging within whatever years you have is an open question. We pursue evidence-supported interventions while being honest about the limits of what is known.
PHI is a physician-led medical practice with board-certified pain and regenerative medicine physicians and surgical-quality infrastructure. The medical rigor and integration with broader interventional medicine differentiate it from many wellness offerings. We do not sell hope; we offer evidence-based and emerging interventions within a comprehensive framework.
There is no fixed timeline. Some patients work with us episodically around specific goals or life transitions; others maintain ongoing relationships with periodic optimization. The relationship is on your terms. We offer packages, but care is individualized and discussed after a treatment plan.
Peptide regulation has evolved over time and varies by specific peptide. Some have clear regulatory paths and clinical evidence; others are in more uncertain territory. We discuss specific peptides honestly during consultation, including evidence base and regulatory considerations.
These tests can provide useful baseline information, and we are beginning to introduce them. Various tests measure different things with varying clinical actionability. We discuss whether specific testing is likely to inform treatment decisions for your situation rather than recommending it as a default.
Insurance coverage and payment options may vary. Please contact our office to discuss your specific plan, available options, and pricing. All pricing is disclosed at consultation.
Yes. PHI regularly treats patients from outside Los Angeles, including Las Vegas, Palm Springs, London, and other international locations. Longevity programs can be coordinated to fit travel schedules.
